摘要:
The invention relates to a method for forming microcavities (118) of different depths in a layer (102) based on at least an amorphous or monocrystalline material, comprising at least the following steps in which: at least one shaft and/or trench is formed in the layer (102) so as to extend through one face (101) thereof, such that two sections of the shaft and/or the trench, in two different planes parallel to the face (101), are aligned in relation to one another along an alignment axis forming a non-zero angle with a normal to the plane of said face (101); and the layer (102) is annealed in a hydrogenated atmosphere so as to transform the shaft and/or trench into at least two microcavities (118).
摘要:
Method for forming a structure provided with at least one zone of one or several semiconductor nanocrystals (13). It consists in: exposing with a beam of electrons (11) at least one zone (12) of a semiconductor film (1) lying on an electrically insulating support (2), the exposed zone (12) contributing to defining at least one dewetting zone (10) of the film (1), annealing the film (1) at high temperature in such a way that the dewetting zone (10) retracts giving the zone of one or several nanocrystals (13).
摘要:
The invention relates to the field of micro- and nanotechnologies. In these techniques, it is sometimes necessary to glue several structures face to face and it is important to be able to check the alignment of the structures. A new method for measuring alignment, which comprises the following operations, is proposed for this purpose: activation of a heating element placed on the surface of the first structure, generation of electronic signals representative of a distribution of temperatures, on the basis of an array of temperature sensitive elements placed on the surface of the second structure, determination of a relative position of the heating element with respect to the array of sensitive elements, therefore of the first structure with respect to the second, on the basis of the distribution of temperatures, in a calculation circuit receiving the electronic signals engendered in the array of sensitive elements.
